Cable-Based Sheet Roll Securing Apparatus with Lock Pin Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for securing sheet rolls or wraps do not effectively prevent theft or unauthorized access, as they lack secure mounting mechanisms to various structures and require significant storage space.
Innovation Solution
An apparatus comprising a flexible or rigid cable with a lock mechanism, allowing secure mounting to frames, walls, or poles, using a cable with a lock notch and pin system, and optionally a numeric or combination lock to restrict access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If storage cases are used to hold sheet rolls, then the wraps are protected and organized, but the storage space required increases significantly and the wraps remain vulnerable to theft
Solution Approach 1:
The patent extracts the sheet roll from the enclosed storage case and mounts it directly to a fixed structure (wall, frame, or pole) using a dedicated holder. This eliminates the need for bulky storage cases while maintaining security through the mounting mechanism and lockable door.
Solution Approach 2:
The holder device serves multiple functions: it secures the sheet roll to prevent theft, provides a mounting structure that can be attached to various surfaces (walls, frames, poles), and incorporates a lockable door for additional security. This multi-functional design replaces the need for separate storage cases.
2Reliability
If storage cases are used to secure sheet rolls, then the wraps are protected from unauthorized access, but the cases take considerable storage space
Solution Approach 1:
The patent removes the sheet roll from the enclosed storage case environment and secures it directly to a fixed structure using a holder mechanism. This extraction eliminates the need for voluminous storage cases while maintaining security through the holder's mounting capabilities and lockable door feature.
Solution Approach 2:
The holder device provides multiple security functions in a compact form: secure mounting to various structures, physical containment of the sheet roll, and a lockable door mechanism. This multi-functionality achieves unauthorized access prevention without requiring large storage space.
3Reliability
If traditional mounting methods are used, then the apparatus is simple to construct, but the sheet rolls are not securely fastened to structures and are susceptible to theft
Solution Approach 1:
The holder device is designed as a universal mounting solution that can be attached to various structures (walls, frames, poles) using different mounting methods. It integrates multiple security features including the mounting mechanism, sheet roll retention, and lockable door into a single device, achieving high security without excessive complexity.
Solution Approach 2:
The holder device is divided into distinct functional segments: the mounting portion that attaches to structures, the body that holds the sheet roll, and the door with locking mechanism. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity.
4Adaptability or versatility
If storage cases are used to hold multiple wraps, then organization is improved, but the cases require considerable space and are vulnerable to theft
Solution Approach 1:
The holder device is designed with universal mounting capabilities that allow it to be securely attached to various structures including walls, frames, and poles. This adaptability is achieved through versatile mounting mechanisms without requiring the device to occupy significant storage space, unlike traditional cases.

AI summary
An apparatus for securing a wrap or sheet roll is disclosed. The apparatus includes a cable in which a first end of the cable is mounted to a structure and a second end of the cable is mounted to a base plate. The apparatus further includes a lock notch provided at the cable. The apparatus has a lock pin removably mounted to the lock notch. The apparatus also has a lock plate mounted to the cable. The apparatus includes a sheet roll mounted to the cable as well. The sheet roll is mounted to the cable by drawing the base plate through an opening provided at the sheet roll. The lock plate is placed above the sheet roll and the lock pin is mounted to the lock notch to secure position of the sheet roll between the lock plate and the base plate.
